A. v0 = 0 m/s, vf = 60mph = $\mathbf{60}\mathbf{\left(}\frac{\overline{){\mathbf{m}}_{\mathbf{i}}}}{\overline{)\mathbf{h}}}\mathbf{\right)}\mathbf{\left(}\frac{\mathbf{1609}\mathbf{m}}{\mathbf{1}\overline{){\mathbf{m}}_{\mathbf{i}}}}\mathbf{\right)}\mathbf{\left(}\frac{\mathbf{1}\overline{)\mathbf{h}}}{\mathbf{3600}\mathbf{s}}\mathbf{\right)}\mathbf{=}\mathbf{26}\mathbf{.}\mathbf{8}\mathbf{m}\mathbf{/}\mathbf{s}$, t = 10s

Using the kinematics equation:

$\overline{){{\mathbf{v}}}_{{\mathbf{f}}}{\mathbf{=}}{{\mathbf{v}}}_{{\mathbf{0}}}{\mathbf{+}}{\mathbf{a}}{\mathbf{t}}}$
